Hello. I can't express how grateful I am to Writeacher for the help. Thank you!

Question

I have one more technical question. Is it necessary to translate the names of authors and their works in footnotes/references if I refer to them in an article to be published in an English journal, for example, I refer to Èâàíîâ Ñ. and his work "Êðóøåíèå Ðîññèéñêîé èìïåðèè" (which is only in Russian), do I have to translate it as Ivanov S.The Collapse of the Russian Empire. or do I leave it in the Russian language in footnotes and references.
Thank you for your attention.

Answer 1

You'd need to leave the author's name as it is in his/her original language, but you can do this with the title:

You may include an English translation of a foreign language title in brackets, outside of the quotations that surround the untranslated title.

This will work whether you are using MLA, APA, Turabian, or any other guidelines.
